Bushing is one of the eminent product of PT Indokarlo Mighty. The company requires some suppliers of
iron cutting services to continue providing high qualified raw materials. The quality is the accuracy of the
intended length of the products which is able to meet the requirements of the requested length. The purpose of
this study is to determine what factors caused the defect on the length of the products. In addition, it is objected
to provide appropriate solutions to eliminate to the factors, so that the number of defected products can be
reduced. This study uses the methodology of Six Sigma improvement models Define-Measure-Analyze-Improve-
Control (DMAIC) to make improvements in the quality of services provided by PT Argatama Multi Agung, while
the improvement phase uses Design of Experiment (DOE) to find the machine configuration that can produce the
best quality products. A significant increase in sigma is obtained from the conducted research.
